A woman and her paramour were arrested here today after she admitted to killing her husband some four years ago alongwith her lover in a Tamil television reality show, police said.

Narrating the murder during the show, Babykala said she and her lover Gowrisankar covered the face of her husband Radhakrishnan, with a plastic cover and suffocated him to death on July 17, 2010.

The victim was in an inebriated state and was in no position to resist. The duo then told relatives that Radhakrishnan had died of "heart attack" and the body was cremated.

However, the law caught with Babykala when her mother-in-law saw the television show and lodged a complaint.

Police said Babykala volunteered to spill the beans in the TV show as her lover had decided to marry another woman "betraying" her.
